Vibration & Ultrasonic for rotating equipment abnormal

Wears in roller detected by HERTZINNO HA3 Acoustic Camera

Today, we’d like to share an unconventional case of abnormal vibration. This took place at a cement plant in Malaysia, where our customer used our HA3 acoustic camera to inspect their conveyor system – a very unconventional application. Although the conveyor generates considerable noise under normal operation, we have verified that when lubrication failure or abnormal wear occur inside, specific ultrasonic signals are produced. By analyzing the signal’s kurtosis, spectral dissimilarity, and stationarity to calculate noise-signal features, we have enabled abnormal wear detection under specific acoustic fingerprint conditions. Here is a video from the site. The user reported that the rapid inspection capability of the acoustic camera was beyond their expectations. In just one minute, camera setup, fault localization, and report generation were completed. We are HERTZINNO, and we look forward to sharing more applications and discussing them with you all.

What kinds of acoustic camera you have used in partial discharge detection

Last month, we use acoustic camera to detect Partial discharge in a substation, we found corona discharge and surface discharge, I believe the surface discharge should be a broken or a dust on the isolator.
